Part(2),

The volume of the snowcone is larger than the volume of the paper cup, the snowcone will overflow when it melts.

Part(3),

The difference in price per cubic inch is $0.0128/in³.

Part(4),

The volume of the cylinder with a radius of 8 inches and a height of 6 inches.

Part(2)

The volume of a cone is given by the formula V = (1/3)πr²h,

where r is the radius and h is the height. The volume of the snowcone is therefore V = (1/3)π(4 cm)²(12 cm) = 201.06 cubic cm.

V = (1/3)π(3 cm)²(12 cm) = 113.1 cubic cm.

Since the volume of the snowcone is larger than the volume of the paper cup, the snowcone will overflow when it melts.

Part(3)

To compare the cost per cubic inch of the two sizes of cereal boxes, we need to calculate the volume of each box and divide the cost by the volume.

The volume of the family-sized box is V = 3 in x 9 in x 12 in = 324 cubic inches.

The cost per cubic inch is therefore $6/324 in³ = $0.0185/in³.

The volume of the regular-sized box is V = 2 in x 8 in x 9 in = 144 cubic inches. The cost per cubic inch is, therefore, $4.50/144 in³ = $0.0313/in³.

The difference in price per cubic inch is $0.0313/in³ - $0.0185/in³ = $0.0128/in³.

Part(3)

The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.

For the cylinder with a radius of 6 inches and a height of 8 inches, the volume is V = π(6 in)²(8 in) = 904.78 cubic inches.

For the cylinder with a radius of 8 inches and a height of 6 inches, the volume is V = π(8 in)²(6 in) = 1206.37 cubic inches.

Therefore, the volume of the cylinder with a radius of 8 inches and a height of 6 inches.

The area of "shaded-region" formed between the two circles having radius as 14 and 6, is 160π square units.

The area of region between "two-circles" can be calculated as area of the "larger-circle" minus area of "smaller-circle".

The "larger-circle" is having radius of = 14 units;

The "smaller-circle" is having radius = 6 units;

So, we can find the area of the region as:

Area = π(14)² - π(6)²;

Area = π(196 - 36),

Area = π(160),

Therefore, area of the region between the two circles is 160π square units.

The correlation coefficient for the data shown in the table is: B. -1.

In order to calculate or determine the correlation coefficient for the data shown in the table (see attachment), we would have to determine the slope of the line based on the points as follows;

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (10 - 15)/(5 - 0)

Slope (m) = -5/5

Slope (m) = -1.

Slope (m) = (5 - 10)/(10 - 5)

Slope (m) = -5/5

Slope (m) = -1.

In this context, we can reasonably infer and logically deduce that there is a negative correlation between the data and the correlation coefficient is -1.

The equation of the straight line shown in the given graph is x = -2

From the question, we are to determine the equation the given straight line in the graph

To determine the equation of the line, we will use the given two points on the line

The given points are (-2, 2) and (-2, -3)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

Substitute the given points

(y - 2) / (x - (-2)) = (-3 - 2) / (-2 - (-2))

(y - 2) / (x + 2) = -5 / (-2 + 2)

(y - 2) / (x + 2) = -5 / 0

Cross multiply

0 × (y - 2) = -5 × (x + 2)

0 = -5x - 10

Add 5x to both sides

0 + 5x = -5x + 5x - 10

5x = -10

Divide both sides by 5

5x / 5 = -10/5

x = -2

Hence, the equation is x = -2

The area of a rectangle is calculated through multiplying its length by its width. consequently, to discover the entire amount of square inches of construction paper Brett needs for his project, we want to calculate the area of each rectangle after which add them collectively.

The area of the primary rectangle is:

16 inches × 12 1/4 inches = 196 square inches

The area of 2nd rectangle is:

10 1/3 inches × 10 1/4 inches = (31/3) inches × (41/4) inches = 126 5/6 square inches

To add those areas collectively, we need to convert 2nd area to a mixed number:

The esteem of the annuity is roughly $21,713.22.

The intrigued (interest) earned on the annuity is roughly $14,513.22.

A. To discover the esteem of the annuity, we are able utilize the equation:

PV = C * ((1 - (1 + r)^(-n)) / r)

where PV is the display esteem of the annuity, C is the intermittent store, r is the intrigued rate per period, and n is the entire number of periods.

In this case, C = $120, r = 4.5%/2 = 0.0225 (since the intrigued is compounded semiannually), and n = 2 * 30 = 60 (since there are 2 periods per year for 30 a long time).

Stepping in these values, we get:

PV = $120 * ((1 - (1 + 0.0225)^(-60)) / 0.0225) ≈ $21,713.22

In this manner, the esteem of the annuity is roughly $21,713.22.

B. The intrigued earned on the annuity would be the overall esteem of the annuity short the entire sum stored over the 30-year period. The full sum kept would be:

Add up to Stores = $120 * 2 * 30 = $7,200

So the intrigued earned would be:

Intrigued = $21,713.22 - $7,200 = $14,513.22

In this manner, the intrigued earned on the annuity is roughly $14,513.22.

Answer: The surface area of the rectangular prism is 424 square meters.

Step-by-step explanation: To find the surface area of a rectangular prism, we need to add up the areas of all six faces.

The front and back faces have an area of length x height, which in this case is 4 x 8 = 32 square meters each.

The top and bottom faces have an area of width x height, which in this case is 15 x 8 = 120 square meters each.

The left and right faces have an area of length x width, which in this case is 4 x 15 = 60 square meters each.

So the total surface area of the rectangular prism is:

32 + 32 + 120 + 120 + 60 + 60 = 424 square meters.

Therefore, the surface area of the rectangular prism is 424 square meters.
